The Occultation of a W=13.1 Star by Asteroid 1999 JU34

This event passes out through the Monterey Bay and the centerline only hits land at Moss Landing. I can get onto the northern limit at Natural Bridges, which is my plan. Kirk plans to try from home which is just a mile or so farther north Natural Bridges. Karl has no chance at this one, from home; the path is too far south and too high rank.

Richard Nolthenius

I observed under perfect moonless skies with good seeing, from 100 yds north of the entrance to Natural Bridges State Park, north of West Cliff Rd. I observed at 4x, and the other settings were standard. I got a clear miss and the data quality is very good.

I used 2 reference stars and the target, and the sky (red). The data looks quiet, low scatter.

The reference star, unsaturated, brighter than the target, and very low noise.

The target star. For only a 4x setting on a 13.0 mag star, this is very low noise data, and a convincing miss.

Zoomed in on the predicted occultation moment. A miss.

Observed from home, and also had a miss at 8x setting. Comparing Kirk's scatter in points at 8x setting, they look virtually identical to my own at only 4x setting. That's good news; I'm happy with the Watec 910hx PAL which is significantly better in noise than my older v3 model NTSC model, which in turn is much better than the older v1 Watec which I used for many years prior to getting the PAL camera last year.
